The Hunter PGV 1" AC Jar-Top Valve with Flow Control is designed for homeowners and contractors who demand reliable performance without the hassle of complicated maintenance. The defining feature of this valve is its threaded "Jar-Top" cap. Instead of dealing with multiple rusted screws in a cramped, muddy valve box, you can simply unscrew the top by hand to access the internal diaphragm for quick cleaning or repairs.
Built from durable, high-grade, UV-resistant PVC, this valve is engineered to withstand the rigors of any residential landscape. It features a rugged, double-beaded diaphragm for a leak-proof seal and an integrated flow control dial, allowing you to manually adjust the water volume to perfectly match the needs of your specific sprinkler or drip zone.

Follow these steps to wire and install your Hunter PGV valve.
Step 1: Plumb the Valve
Using Teflon tape, thread your 1" PVC male adapters into the inlet and outlet ports of the valve. Ensure the directional arrows on the valve body point in the direction of the water flow.
Step 2: Connect the Common Wire
Identify the two wires attached to the solenoid. Connect one of these wires (it does not matter which) to the common wire returning to your irrigation controller using a waterproof wire nut.
Step 3: Connect the Station Wire
Connect the remaining solenoid wire to the specific station/zone wire running back to your controller using a waterproof wire nut.
Step 4: Adjust the Flow Control
Turn on the zone manually. Rotate the central flow control handle to fine-tune the water output until your sprinklers or drip emitters are operating at optimal pressure.
What does a "Jar-Top" valve mean?
A Jar-Top valve features a large threaded ring that holds the upper body in place, allowing you to unscrew the entire top of the valve by hand, just like opening a jar.
This completely eliminates the need for screwdrivers and makes cleaning or replacing the internal diaphragm incredibly fast and easy.
Why do I need a valve with flow control?
Flow control allows you to manually dial down the volume of water passing through the valve. This is highly useful for optimizing pressure for sensitive drip systems or preventing excessive misting in sprinkler zones.
By turning the central handle, you can easily balance the flow to exactly match your landscape's needs.
Can I use this valve with a battery-operated timer?
No, this valve includes a standard 24-volt AC solenoid and must be wired to a plug-in residential irrigation controller. It will not work with a battery-operated timer unless you swap the solenoid for a DC latching version.
How do I manually turn this valve on without the timer?
To manually activate the valve, firmly grasp the black solenoid cylinder and turn it a quarter-turn counter-clockwise. To turn the water off, twist the solenoid clockwise until it is hand-tight.
Why is a Jar-Top valve highly recommended for mid-spring system maintenance?
In mid-May, homeowners must flush their systems to clear out sediment that settled over winter. The tool-free Jar-Top design allows you to open the valve in seconds, easily clean the diaphragm, and prevent clogs before summer watering begins.
Traditional screw-top valves can be frustrating to open in wet spring soil. The simple twist-off cap of the PGV Jar-Top makes this critical seasonal flush much faster and less labor-intensive.
